Tim Harrison and Kathy, his wife, started Lighthouse Depot, Lighthouse Digest and the Lighthouse Foundation.

Don Devine eventually purchased the Lighthouse Depot and it's catalog operation, Tim & Kathy kept the Digest and the Foundation. There was still cooperation between the Depot and Tim & Kathy's interests up to the end.

Lighthouse Digest has been selling pieces that were either part of Tim's collection or are selling items on behalf of another collector.
